Definitely 2deg with no spacers under either RF or RR blocks.
Shims are 0.5mm thick which equates to 0.75deg per shim (1.5deg per mm) - if you want to get really accurate it's actually moves between 0.71 & 0.78deg due to the swept angle changing too but most people use 0.75 without issue
Same for the ZX5 as the hinge pin holder / wishbone width is the same, see FABs sheet on Petit Lazer setups section
Hope that helps.
